ES9023 / WM8804 S/PDIF "Subbu DAC V3" GB Interest

[pinnocchio]

Would the balanced kit be easy to interface with an EXAU2I USB to I2S module?

Thanks

Hi there!

If I want to use i2s and sometimes also SPDIF as input can I chose between these modes or do I have to choose now which way I want to use the Subbu DAC v3 ?

Because on the spreadsheet at "Inputs" for the GroupBuy it says "-I2s pads: omit WM8804 for I2S use **"

So I need to omit the WM8804 Chip if I want to use I2S! Or ist it possible to switch easily between I2S and SPDIF as Source with the WM8804 Installed on the Board!?
This would be optimal!


Thank you in advance!

Greetings Ron

Hi,

is there any chance to install Hirose's U.FL socket for I2S input? This possibility would be very interesting for WaveIo and Ian I2S Buffer owners.
Probably the best I2S board to board connection. You can't miss it in your wonderful DAC.

Thanks

Hi,

I have filled the spreadsheet. I will build one stereo SE Dac. I hope I did it ok...

I use Ian's BIII adapter kit with good results to connect subu dac to either wave, amanero or ian's reclocker using the u.fl sockets.

First of all thanks to Korben69 for organizing this, much appreciated.

Added myself to the list now but might fiddle around with it until the GB closes not sure if I would like to try the balanced version as well.

There seems to be a formula missing in the parts prices, BAL and PSU prices are the same in USD and EUR.

All the best, Stefan

Hi Do

Yes, both BAL & SE versions could be fed by I2S stream.
Standard I2S Pins as follow : BCLK - LRCK - DATA - MCLK.
My goal is a BAL version in I2S Mode using Amanero's USB stick

Hi rondadon and hirez69
Good points concerning I2S mode and U.FL connectors.
Subbu will provide U-FL footprint/socket on DAC V3 PCB.
About switching from SPDIF to I2S, I summon "Moderator Emeritus" for the answer

Hi jcastellano, swalter and other who have signed up the spreadsheet

We've crossed 315 units today !
Remember that we, probably, will soon close the GB (October 18th)

I've to find some clever solutions for Parts Kits delivery.
Maybe some "local" relays will be really usefull.
I prefer sending one insured & tracked parcel to one member vs a lot.
That's the idea, your opinion are welcome
Thank you skylab, he has spontaneously offered his help.

As previously told, I expect prices cutdown due to the reached quantities.
Jean-Paul and Subbu are still testing parts.
BTW I'll update Parts Kits prices as soon as they have finished this task.

Thank you Stefan, prices are now the right ones now.
But, they aren't final prices, but those paid during last Parts GB.
I've locked some cells in the spreadsheet.
